Specification of Letters Patent. Patented Apr. 6, 1915.

Application filed ma 21, 1914. Serial no. 839,991,.

T all whom it may concern Be it known that we, WILLIAM H. BARRoN,"

J r., a citizen of the United States, and resident of Atlantic City, in the county of Atlantic and State of New Jersey, and CARL LESEMAN, a citizen of the United States, and resident of Egg Harbor City, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in Carpenters Tools, of which the following is a specification.

Our invention relates to tools for the use of carpenters, stair builders, cabinet makers, and others, and the main object is to provide a tool which is adapted for a wide range of use 'as a marking gage, and also as a scriber, to mark work on regular or' irregular lines. Q 1

A further objectis to provide such a tool which is adapted to accurately mark the skirting board of a stairway in one opera tion, with one marking.

A further object is to provide a tool of this type which is adapted for use at either of its ends, and the marking elements at which ends are independently adjustable.

A. further object is to so construct the tool as to be capable of scribing circles,' and also, in conjunction with a square, for scribing ellipses of any desired dimensions.

()urinvcntion is fully described in the following specification, of which the accompanying drawings form a part, in which the separate parts are designated-by the same reference characters in each of the views, and in which 1 Figure 1 is a perspective view of the tool; Fig. 2 is a longitudinal section thereof; Fig. 3 is a view of the operation of marking the positions of risers, in the skirting board of a stairway, with our tool; Fig. 4 is a similar view showing the operation of marking the positions of the treads therein; Fig. 5 is a view of the skirting board in place and showing its connection with the base-board;

Fig. 6 is a view of the method for using our 7 tool as a scriber for circles; and Fig. 7 is a similar view for use in scribing ellipses.

Our invention consists of a straight rod a, having a wheel or roller a at one end thereof, and on said rod we mount an adjustable marking-wheel b, an adjustable needle-point c. and two adjustable guide-pins cl and d carried in suitable blocks 6 0 d and 61 respectively, each of which has a set-screw therein. a

In Fig. 3 is shown-the position of a skirtlug-board, with respect to a stairway, for marking the positions of risers, the said board being shown at f, the risers at f and the treads at 7, the gage being set at the required point, whereby the marking-wheel b, is at a distance from the wheel a equal to the distance between the vertical planes of the risers and, the riser lines may then be cut or scratched with the needle-point c which has been adjusted with reference to the wheel a this being repeated for all the risers, as indicated in Fig. 3, and it will be noted that the lower end of the skirtingpositions therefor, the gage is again set so that the marking-wheel b is at a distance from the wheel (1 equal to the distance be-' tween the horizontal tread planes, the skirting-board having been slid upwardly on the nosings of the treads into the position shown in Fig. 4, after which the positions of the' treads are marked, the wheel or roller a moving over the floor or successive treads and the gage being maintained in vertical position, whereas in the marking of the risers, the roller (1 moved over the risers of the stairway and the-gage was maintained in horizontal position. After the said po' sitions have been so marked, the holes for the tread nosing are bored, and the skirtingboard grooved therefrom for the treads and then the risers, and said board is ready for assembling on the stairway.

For scribing circles, all-that is necessary is to move the wheel 6 and needle-point c apart a distance equal to the radius of the circle, saidneedle-point serving as the pivot for the circular movement .of the marking wheel .7), and irregular outlines may be scribed with the gage by the use of either the needlepoint or the marking wheel, in

conjunction with the roller a which guided over the irregular surface whlch it is desired to mark on a board or the like.

sions within the limits of the rod a, the 'method of so doing being to draw line mw, intersect the same with perpendicular line z-2, set' the pin 03 at a distance from the wheel 1) equal to one-half the shortest diam eter, and the pin d a distance from said wheel equal to one-half the longest diameter, after which a square is arranged along the lines ww and 2-2, as shown, and one quarter of the ellipse may be marked by maintaining the guides 03 and (Z in constant contact with the square, and moving the wheel I) from the line 2-2 to the line m:v, the position of the square being changed for each of the three remaining quarters of the ellipse.

It will thus be seen that our device is capable of great latitude in use, is very simple in construction, well adapted to the purposes for which it isdesigned,and comparatively inexpensive and, reserving the right to make all desired changes in the same, within the scope of the following claims,

What we'claim as new, and desire to secure by Letters Patent, is 2- 1. A tool of the class described. comprissaid block arranged transversely to the axis of said rod.

2. A tool of the class described, comprising a rod, one end of which is forked, a shaft in said fork arranged in an axial plane of said rod, a roller on said shaft arranged in an axial plane of said red at i right angles to said first named plane, a block adjustable on said rod, a wheel on said block and arranged transversely to the axis of said rod, and a age-block adjustable on said rod, said gagelock being-provided with a needle-point thereon.

' In testimony whereof we have signed our" names to this specification in presence of the subscribing witnesses. I
